A square pyramid is shown:



What is the surface area of the pyramid?

A. 2.46 square feet
B. 8.76 square feet
C. 5.16 square feet
D. 1.56 square feet

Answers

Answer:

B.76 square feet

Step-by-step explanation:

SA=B+L

Answer: B)  8.76 square feet

=========================================================

Explanation:

The base is a square with side length 0.6 ft, so the base area is 0.6*0.6 = 0.36 square feet.

Each lateral triangular panel has base 0.6 ft and height 7 ft. The area of one triangle is 0.5*base*height = 0.5*0.6*7 = 2.1 square feet

So four of these triangles combined give a lateral surface area of 4*2.1 = 8.4 square feet. Add this onto the base area to get 8.4+0.36 = 8.76 square feet of total surface area.

During the holiday sale, the store discounted all items 1/3. What is the discount on a $19.95 item? plz help me

Answers

Answer:

Discount Final Price Each

1/3 off $ 19.95. $ 13.30

Step-by-step explanation:

I think its 13.30

Answer: $13.30

Step-by-step explanation: If you multiply 19.95 by 1/3 you will get the answer 6.65, that is the amount that is taken off. So next, you can just subtract 6.65 from 19.95.

19.95-6.65=13.30

So that is the answer, with the discount the item is now $13.30

Carl has three lengths of cable, 5/6 yard long, 1/4 yard long, and 2/3 yard long. If he uses 1 yard of cable, how much cable is left?
Please explain how you did it :3

Answers

He would have 9/12 yards left over because you have to create a common denominator which would be 12. so for 5/6 you would multiply by 2 so you have 10/12. 1/4 you have to multiply by 3 so you get 3/12. and 2/3 you have to multiply by 4 so you get 8/12. then you add them 10/12+3/12+8/12 = 21/12 which simplifies to 1 9/12 and because he used 1 yard he is left with 9/12.
final answer: 9/12 yards
